I purchased this long skirt from index. The back of the waist is elastic, making it very easy to wear♪ It's made of a thin material but has a lining, making it the perfect item for the coming season (´∀｀) I've worn it 2-3 times, but my style has changed and I no longer wear skirts, so I'm selling it. Brand...index Color...Navy Material...Outer: 100% polyester 　　　　Lining: 100% polyester Size...M Damage/Stains...None that are noticeable Please understand that this item has been stored at home before purchasing.
